[libvirt] [PATCH] storage: Fix volStorageBackendRBDRefreshVolInfo
by Yi Li
Fix the return value status comparison checking for call to
volStorageBackendRBDRefreshVolInfo introduced by commit id f46d137e.
we only should fail when the return is < 0. -ENOENT, -ETIMEDOUT will
ignore according commit id f46d137e.

[libvirt] virsh blockresize syntax is inconsistent with vol-resize and somewhat dangerous
by Tim Small
Hello,
virsh has two commands which can be used to resize block devices -
"blockresize" for volumes in use by and active guest, and "vol-resize"
for volumes which are not in use.
The vol-resize syntax allows to specify the size as a delta (increase or
decrease vs. the current size), and also refuses to shrink a volume
unless the "--shrink" argument is also passed.
Most other tools which can be used for block device resizing (outside of
libvirt) also have similar "--shrink" argument requirements when
reducing the size of an existing block device. e.g. ceph requires
"--allow-shrink" when using the "rbd resize" command.
The lack of such a safety device makes "blockresize" a foot-gun (which I
recently found to great effect when I typoed the domain name to another
valid domain).
It seems I am not alone in making this error e.g.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902171
One possible solution would be to make a new command e.g. "domblkresize"
or perhaps "live-resize", which implement the "--shrink" and "--delta"
behaviour to make it consistent with "vol-resize" syntax, and mark the
"blockresize" command as deprecated in the documentation and help (so
that existing automation which depends on the current behaviour doesn't
break).
Any thoughts? Should I open this as an RFE?
Thanks,
Tim.

[libvirt] [PATCH 1/1] qemu: hide details of fake reboot
by Nikolay Shirokovskiy
If we use fake reboot then domain goes thru running->shutdown->running
state changes with shutdown state only for short period of time. At
least this is implementation details leaking into API. And also there is
one real case when this is not convinient. I'm doing a backup with the
help of temporary block snapshot (with the help of qemu's API which is
used in the newly created libvirt's backup API). If guest is shutdowned
I want to continue to backup so I don't kill the process and domain is
in shutdown state. Later when backup is finished I want to destroy qemu
process. So I check if it is in shutdowned state and destroy it if it
is. Now if instead of shutdown domain got fake reboot then I can destroy
process in the middle of fake reboot process.
After shutdown event we also get stop event and now as domain state is
running it will be transitioned to paused state and back to running
later. Though this is not critical for the described case I guess it is
better not to leak these details to user too. So let's leave domain in
running state on stop event if fake reboot is in process.
As we don't know when stop event really arrive let's move resetting flag
after starting CPUs - at this point stop event should be handled.

[libvirt] [PATCH 0/2] Deprecate implicit filters
by Vladimir Sementsov-Ogievskiy
Hi all!
Max's series to fix some problems around filters consists of 42 patches.
I'm sure that we didn't find all bugs around filters, and that filters
would be a constant source of bugs in future, as during developing new
feature nobody will consider all possible cases of dealing with filters
(OK, somebody will, but it's hard).
So, I'm thinking about starting some deprecations which will help us to
simplify all the picture at least in not far future. So, I'd really want
to deprecate implicit filters, ->file child based filters (move all
filters to use backing child), filename based interfaces (use node-names).
Most simple thing is implicit filters, so let's start from them.
drive-mirror don't support filter-node-name, so I propose to deprecate
it at all, together with drive-backup, instead of adding support of
filter-node-name, what do you think?

[libvirt] [PATCH RFC 00/40] qemu: Add support for incremental backups
by Peter Krempa
This series is my attempt to clean up and finish incremental backup as
it was last posted in v10 here:
https://www.redhat.com/archives/libvir-list/2019-August/msg01018.html
Out of that series, patch 1 was dropped for now and I'll revisit it
later. The patches adding docs, xml parsing and job plumbing were
partially modified and stripped of currently unimplemented
functionality.
The qemu implementation was completely rewritten.
Of the new series first 28 patches are cleanups and can be reviewed for
pushing.
The main incremental backup functionality is not complete yet and should
not be pushed right now not even in experimental (disabled [1]) state
due to possible API changes:
- figure out whether we want our own event for the backup job or want to
deal with the domain job event
- if we go with the domain job event everything must be rewritten as a
single domain job
- otherwise plumbing for the event must be added
- documentation must reflect the above
after that will be sorted out the following needs to be done until we
can finally enable it:
- more testing. I merely verified that qemu generates files/exports NBD
- blockjob support for bitmaps (for commit/pull/copy)
- snapshot support for bitmaps
- merging of bitmaps accross backing chain entries
- figuring out a more elegant way to do the bitmap for the backup than
creating two, one for the 'store' (for NBD server) and one for the disk
itself.
- ...
Until then the following XML can be used to enable the functionality for
testing without any guarantee [1]:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<qemu:capabilities>
<qemu:add capability='blockdev'/>

[libvirt] [PATCH 0/2] virt-aa-helper for shmem device
by Christian Ehrhardt
Cole was recently adding a few of the usual apparmor suspects to BZ 1761645
and I was taking a look at the low hanging fruits of it today. It isn't
perfect, but would resolve the reported issue - so I'd appreciate a
review.
Limitations:
- One could break the path creating elements in qemuBuildShmemBackendMemProps
and qemuDomainPrepareShmemChardev into extra functions and then use those
from virt-aa-helper. But I haven't done so yet and unless it is strictly
required consider it too much for what we want/need to achieve here.
- I haven't covered hotplug of shmem devices yet, it seems there is no
infrastructure for their labels yet and I wasn't sure how important
shmem-hotplug would even be to anyone.
